Thermodynamic and structural characteristics of water (0.07-1 g per 1 g of silica) bound to nanosilica A-380 (SBET = 378 m2/g, primary particle diameter 7.2 nm) alone or on co-adsorption with chloroform alone or in the mixture with DMSO or acetonitrile were determined using 1H NMR spectroscopy with layer-by-layer freezing-out of water at 200-273 K and NMR-cryoporometry.
